Excise invoice xxxx has already been posted for vendor xxx

Hello,

We have a situation wherein when we try to reverse excise invoice system is giving above mentioned error with Message no. 4F107

Process:-

1. Mvt type 501 is used for GR (Material is non valuated)

2. T.code J1iex is done (excise invoice posted)

3. original material document is cancelled

4. j1iex (Excise cancel) option is selected and error pops up with excise invoice is already posted

Material is maintained in j1id, reversal sequence is checked, material document is reversed with mvt type 502 but I am not sure what I am missing

Any suggestions?

Thank You

Nishu
